MACHINE FO R ERECTING WALLS OI BRICK AND THE LIKE.

Specification. of Letters Patent.

Patented Mar. 28, 1922.

Application filed December 14, 1918. Serial No. 266,832.

To all whom it may concern:

Be it known that l, STEWART KAYn, a sub ject of the King of Great Britain and Ireland and the Isle of Man, and a resident of Edinburgh, Scotland, captain in the itoyal Engineers, have invented new and useful hlachines for Erecting Walls of Brick and the like, of Which the following is a specilication.

This invention has reference to a machine for erecting walls of bricks and the like and comprises an upright structure having a horizontal structure the distance of which from the ground level alters as the successive courses of bricks are laid. The horizontal structure is provided With a pendant apparatus termed the laying mechanism which comprises a laying? chain (or chains for double walls) of the caterpillar type of mechanism. The upright and horizontal structures are provided with conveyor chain mechanism.

The bricks are placed in a receptacle or hopper and elevated therefrom by means of a conveyor which elevates the bricks to the said horizontal structure, and then conveys them to the laying mechanism.

The Whole apparatus is carried on a vehicle which also carries the brick recepta cle into which the bricks to be laid are placed in tiers or columns.

The machine is so operated from a motor or the like carried by same that bricks are fed one at a time from the hopper containing same into the conveyor chain elevated by the latter to the horizontal structure, transferred from the conveyor chain to the laying chain by transferring mechanism nd then laid in the position to form the wall by the said laying chain. Mortar or the like is also carried by the machine in a tankand is placed on the bricks as they are laid.

There are two ways in which a building may be built and one Way consists in building from the inside of the building being erected While the other way consists in building from the outside of the building being erected.

The situation of the proposed building sometimes necessitates building from the inside and sometimes the building may be built from the outside. Further in some parts of Great Britain (for instance in Scotland) it is usual to build from the inside While in other parts (for instance in England) the trade custom is to build from the outside.

The machine according to this invention under one modification, adapted to build from the inside, while, under another modification, is adapted to build from the outside of the proposed building.

According to the first modification the machine comprises a vehicle provided with a vertical, rotatable telescopic, pillar or girder structure having at its upper end a horizontal arm or frame which carries a vertical and downwardly projecting frame capable of being moved along the horizontal frame. Conveyors are provided to elevate the bricks, blocks and the like to the horizontal arm or frame, then along said arm or frame, and from there to their position and mechanism is also arranged to place the mortar or the like on the bricks and to place the bricks in their position on the wall.

This machine is particularly adapted to build the four Walls of a building such as a house, villa, or factory, and when the telescopic structure is collapsed the vehicle may be run into its position, the Walls built, and as the Walls rise the structure carrying the conveyors is extended and then the structure is collapsed again, and the vehicle may be run out through the doorway. The machine is preferably operated by means of small motors or the like.

According to the second modification the machine differentiates from the beforementioned machine in that the vertical girder structure is not rotatable nor is .it telescopic but is a fixture (While the operation of building is being performed) to the vehicle carrying same While the horizontal arm consists of a cantilever frame capable of being moved vertically up and down on said vertical girder structure. The laying mechanism carried by the cantilever frame is not capable of travelling horizontally along the said frame but is only capable of being moved slightly along same for the purpose of adjustment. The laying mechanism itself is also improved or modified in design and so also is the conveyor chain, the feeding mechanism and the carriage or vehicle travelling mechanism.

These and other improvements will be hereinafter more particularly described and referred to.

In order that others skilled. in the art to whichthis invention relates may properly understand the same I have hereunto appended 12 sheets of explanatory drawings in which F1gure 1 isa diagrammatic side elevat on oi. the lower portion of a machine as conience of illustration and Figure 2 is a continuation oft-Figure 1; the machine being shown in the extended position.

Referring to these drawings. In carryinpythe improvements of this in- ;rention into effect or practice under the first modification a vehicle 1 adapted to run on rails 9 is provided with a turntableB which .mounted on a shaft 10. rice proper consists of a plunger or ram carries a vertical telescopic pillar or girder structure i.

Preferably the turn-table 3 is rotated intermittently step by step, a predetermined (li nce and at the proper times by means oi worm and worm wheel gear operated automatically from a motor 5 by means of suitably arranged contacts.

is provided with a llhe turntable a) brick feeding device consisting of a removable and rotatable container or receptacle 6, l lies. '7 and 5% having a plurality of compartments 7.

Preferably the receptacle 6 is provided iviJh eight compartments 7, and with means whereby each of the compartments in turn register with the feed device proper. The receptacle 6 rests on rollers 8 carried in. suitable bearings on the standard 9, and is The feeding de- 11 rcciprocated from the motor 5 by the crank and link 12. This ram 11 works on rollers 13 carried by the brackets 14. The

bricks 15 are stacked in each compartment 7 and are supported, when not registering with the feed device proper, by means of an angled hinged shutter plate 16. When a compartment 7 is over the ram 11 the plate 16 is swung outwards by suitable stops or catches 17 from below the bottom brick 15 of the stack and the bottom brick rests on the upper surface of the ram 11 when same is forward; When the ram 11 is drawn back. into the position shown by Figure 1 by means of the crank 12 the stack of bricks falls down so that the bottom brick rests on the table or support 18. The ram 11: now moves forward and pushes the bottom brick into position 19. bottom brick now becomes the bottom brick and rests on the upper surface of the ram 11. The ram is now drawn back and the stack of bricks falls down as before. The ram. moving forwards again pushes the brick in position 19 to position 20 and the brick in position at the bottom of stack to position 19. It will thus be seen that all the bricks in this compartment 7 are succes sively t'ed "forwards on table 18. When one compartment 7 is exhausted the receptacle 6 is rotated one eighth of a revolution so as to bring the next compartment 7 into the feeding position, and so on each compartment in turn being brought into position. The means for rotating'the receptacle G the correct distance preferably con sists of an endless chain 21 passing over sprocket wheels 22 and 23 driven from the motor 5 by the gearing 24 at the desired speed. This chain 21 is provided with a projection 25 adaptedto engage the projections 26 carried by the receptacle, 6. It will be readily understood that when the The second projection meets projection 26 the re ceptacle is rotated a part of a revolution and when projection 25 moves away from projection 26 the receptacle is at rest and remains at rest until the projection 25 has travelled round the sprocket wheels 22. and 23 back to engage the next projection 26. When all the compartments 7 are empty the shaft 10 is moved downwards clear oi? the receptacle 6 by means of the rack and pinion 27 and handle 28. V

The empty receptacle 6 is now removed and a full receptacle is substituted. The shaft 10 is now moved up again and the operation of feeding the bricks is repeated.

The telescopic structure 4 is provided with bottom wheels 29, Fig. 1 round which a conveyor chain passes. The wheels 29 are driven from the motor by the gear ing 24 and chain or like device 31.

The upper end of the telescopic structure 4; is provided with a horizontal frame or arm 32, Fig. 2 and the conveyor chain 30 passes over rollers 33 and over a loose wei hted roller 34 which takes up the slack oi? the chain 30 as the structure is collapsed.

The telescopic structure 4 preferably consists of a girder frame-work and is extended the requisite amount by means of hydraulic pumps and connection 35, Fig. 1. p

The chain 30 preferably consists of a double set of links 36, Fig. l. provided with hinged or pivoted plates 3?, Fig. adapted to remain always in the norizontal position, and to carry between them the bricks 15. When the chain is passing up the structure l the bricks on the table 13, Fig. l, are led on to the plates 37 and carried by these plates 37 along the horizontal frame 32 and then transferred to the laying chains and mechanism. This laying mechanism consists oi? a carriage provided with wheels 38 Figs. 2 and 3 adapted to run on the rail members 33-) of the frame 32. The carriage consists oi: a triangular frame or arms at), which carry between them a pivoted ring (or gamblin wheel) 41 provided with a race 42 on which rollers a3 oi: a layin structure are adept ed to run and turn. It will be readily under stood that the turn-table rotates through an angle l5 and carries round the horizontal frame 32 the laying structure a l will re main in the same vertical plane. The laying it lillllSDl also consists oi two chains 45, l s. and 3, which n. s over wheels 4-6 and ii-l" carried by the SllTlK/illl't. and the bricks are transierred iron. the conveyor chain 30 to the laying chain by means of spring arms 48, Figs. 9 and it). and a drop plate secured to the frame 49 so as to be capable of rotating in a horizontal plane and having flanges 50. The spindle 51 of the rollers l6 carries a star or sprocket wheel 52 the arms of which engage the limb 53 ot a lever 53, 56. The limb 56 is provided with a roller 54 adapted to bear on the plate 49. Each arm of the star wheel 52 in turn moves the limb 53 01' lever into the position shown by dotted lines and consequently the plate 49 is pressed down by the roller 54. The inverted cone 55, as plate at?) is lowered forces apart the arm 48 and the bricks in positions 57 and 58 are gripped between these arms 48 and the flanges oi? the plate 49. The plates 37 of the chain 30 pass from under the bricks while in positions 57 and 58, and these bricks are lowered on to gripping plates 59. Fig. 14, provided on the laying chains The cone 60. Figs. 5, 9 and 10 re leases the bricks from the gripping arms 48 and flanges 50 and the spring 61 and telescopic rods 62 brings the frame 49 and mechanism to the upper position ready to lower the next pair of bricks. The bricks are carried down by the chains 45 and placed in position on the wall. As shown there are two chains Fig. 2 which erect a double wall.

lVhen the horizontal frame is inclined at an angle other than a right angle, to the laying chains (or to the wall being built) it is necessary that as the bricks are trans terred from the chain 30 to the chains #15 that they are turned into the proper position for placing on the chains 45.

This mechanism consists in fitting to the distance piece 53, Figs. 9 and 10. between the wheels 46 a spindle or rod 64 provided with a spiral web- 65.

l V hen the chains 45 are at right angles to the conveyor chains 30 a collar 66, provided with a V or like shaped groove and carried by an arm or bracket (37, does not engage with the spiral web 65 so that the transferring mechanism has a direct drop and re turn. Assume, however, that the chains a5 and consequently also the spindle 51, star wheel 52 and levers 53 and 56 are at an angle other than a right angle to the conveyor chain 30 and the drop plate is drawn down as stated. On such downward movement the groove in the collar 66 carried by the arm 67 attached to said drop plate, comes in con tact with the spiral web 65 on the rod (A which web turns the drop plate about i ts support to the required extent before the bricks carried thereby come over the chain 45.

Atthe lower part of the laying mechanism the chains 45 pass over wheels 47, Figs. 3. i2 and ill, and place the bricks on the wall.

These wheels 47, l3 and 14;, are provided with plungers 68 having springs 69 and having tapered or angled ends 70 which are acted upon to press the brick into position by a pin or the like 71. This pin '71 is a fixture in the frame 44 and acts on the tapered ends 70 as they pass below same.

The projections 72 on the Wheels 47 form the teeth for engaging the chains 45.

The niortar is led from. the tank i i to the upper surface of the co or hrlcks already laid by ineansoi a pip so that just bea laver or" mortar is placed below same.

Another pipe 76 conducts the mortar from the tank 74; to the spar-ea hetwuin the bricks so that just before the bricks are laid in position layer 05 mortar inserted between their ends.

The laying mechanism is provided with telescopic c uide 'ods 7T. Fig-rs. ll and lid, having-a roller 78 at its lower end adapted to run in a guide rail 75-) arranged along the wall being built.

After one course of bricks has been laid the telescopic structure is extended the desired amount by means oi? suitably arra. ged contacts which operate the hydraulic niechanisin 35, Fig. 1, or other suitable hoisting gear.

The rails 2 upon which the vehicle 1 are laid end to end oi the building runs to be walls. In operation the vehicle l. connnerces near the end of the one side wall with the horizontal arm 32 at right angles to the rails 2 and side wall. As each brick is laid the ve hicle 1 moves forward the vehicle 'trawlling along the rails parallel with the side walls. When the vehicle has reached the limit of its travel there is a small portion of the wall to be done up to the corner and this is cilecied by rotating the horizontal arm the laying mechanism remaining parallel with the rails 2 and the bricks while being transferred from the chain to the chains be ing turned.

The movable carriage or member of the horizontal frame 32 moves outwards along the said frame a suflicient distance while tl' frame 32 is rotating. VVhcn the one course on the one side wall is completely laid the horizontal arm 32 still rotates and the course is laid on the end wall and similarly on the first portion of the outer side wall up to the point where the horizontal arm is at right anglesto the rails 2. The vehicle 1, then travels back and then the frame rotates until the course on the other end wall is laid and then the course on the first side wall is completed.

The vehicle is now in the position it first started from and the one course is laid. The telescopic structure t is extended the desired height (the thickness of brick and mortar) and the ne-it course is laid in a similar manner.

the shorter of the two overhanging ends of the cantilever frame '32" and which by means of spur or like gearing 82. Figs. 15 and 16. drives a horizontal shaft carried. by the cantilever frame 52. This horizontal shaft 8 3 drives by means of bevel or like gearing 84 a vertiwal and telescopic shaft 85 which is carried by the ."ertical structure 4 and which drives a horizontal shaft 86 by means of bevel or like gearing 87. This latter horizontal shaft 86 drives by means of a vertical shaft 87" and bevel gearing 88 another horizontal shaft 89 at a lower ,evel on which is mounted a rain 90.1 m. 15. which by means of a roller 91 hearing against its cam surface and carried by a spring controlled lever 92 reciprocates the ram or plunger 11 connected to the lever 92 by means of a link 93. Lever 92 is pivoted at its lower end and as it swings about its pivot under the action of the cam it forces f0rward the plunger 11 to which it is connected as aforesaid, the return movement of the lever 92 and therefore the plunger 11 being effected by the compressed spring 92. This ram 11 is adapted to force the bricks one at a time out of the box like reservoir 6 into the conveyor 80. This mechanism is so timed by the arrangement of the gearing that at the instant one of the links of the conveyor 30 is opposite the ram 11 the brick is forced into the spring clip 81. The bricks are carried by the conveyor 30 from the feeding mechanism up the vertical structure 4 and along the cantilever frame 32" to the laying mechanism suspended from said cantilever frame. This laying mechanism consists of two side cheeks 94. Figs. 18 and 19, provided with rollers 95 adapted to rest on the girder rails of the cantilever frame 32*. The two side cheeks 94 are connected by a bridge piece and are provided with a screwed rod 96 having nuts 97 so that the position of same can be adjusted on the cantilever frame 32*. The return pulley or drum 33 for the conveyor chain 30 is also mounted between these side cheeks 94 on adjustable bearings 98 so that its position can be adjusted also. A. downwardly hanging frame 44 is supported from these side cheeks 94 and is provided with preferably three rollers or drums 46" and 47" round which a laying chain 45 passes. These rollers 46 and 47 are arranged one 46 near the upper part of the hanging frame 44 and just below the cantilever frame 32 and the other two 47 a at a lower level and one on each side of the hanging frame 44: The two lower rollers 47 are provided with adjustable bearings 99. order that double walls may be built there are two laying chains 45 arranged side by side and passing round the three rollers 46 and 47*. Mechanism is arranged to transfer the bricks from the conveyor 30 -to the laying chains 45 Figs. 18 and 19. This mechanism consists of two horizontal transverse spindles 100 and 101 arranged. in

alignment between the side cheeks 94 one passing through each cheek with a space between the inner or adjacent ends of: the spindles 100. A transverse spindle 107*,

s. 16. 19 and 21. extending between the cheeks 94, is rotated by means of bevel gearing 104, spur wheels 102 and the shaft 83 which is driven from the motor 5*.

Pinions 106 mounted on the spindle 107 drive wheels secured to the spindles 100 and 101.

On each of the spindles 100 and 101 a cam 107 is nuninted. These two cams 1.07 are 1 ,-"o .'i 'led with a reciprocating pusher rod 108 pivoted to said cams and which as the cams 107 rotate engages with the conveyor chain 30 by means of a projection 108", Fig. 20 and pushes same along the distance of two links. Between the cams 107 two vertically reciprocating rods 108 are mounted each within a sleeve or tube 109 which also contains a spring 110 adapted to press the rod 108 downwards. The rods 108 are held up against the action of the springs 110 by arms 11.1 provided with rollers 112 engaging the cams 107. As the cams 107 rotate the cam surfaces permit the rods 108 to move downwards to pass through openings in the links of the conveyor chain 30 and to eject the bricks on to the laying chains 45. The laying chains 45 are travelled from the aforesaid, short horizontal spindle 101, see 100 Fig. 18 by means of a crank disc 113, Fig. 18, mounted on the spindle 101 and having a connecting rod 1.14 which is also connected to the end of a lever 115 provided with a pawl 116 adapted to engage the teeth of a 105 ratchet wheel 117 mounted on the spindle 118 of the roller 46 of the laying chains 45, This mechanism is so arranged that one of the links of each laying chain 45 exactly registers with the links of the conveyor 110 chain 30 so as to receive the bricks ejected therefrom. The lever 115 carrying the pawl 116 of the upper roller spindle 118 is con nected by a link 119 to a downwardly recip rocating rod 120 having a foot 121 at its 115 lower end. This foot 1.21 is adapted to actuate vertical rods 122 controlled by springs 123 by means of bellcrank lever and rod mechanism 124. These rods 122 eject the bricks from the laying chains 45* on to 120 the wall being built. To enable the bricks to be laid in rotation to form each course the whole machine carried by the vehicle 1" moves along the rails 2 This travelling movement is almost continuous but not quite. 125 There is a very short period of rest to enable the bricks to be laid. This motion is accomplished from the shaft 86 driven from the before mentioned telescopic shaft 85, see Figs. 23, 24 and 25 carried by the vertical girder structure 1. Said'shaft 86 by means of spur wheels125, Figs. 24 and 25, drives a shaft 127 provided with two crank discs 1% each of which is connected by means of a link 129 with the end of a lever 1330 provided with a-pawl 131 adapted to rotate intermittently a ratchet wheel 132 mounted on a spindle 133. These two ratchet wheels 132 rotate the spindle 133 with the period ofrest as desired. This. spindle 133 is provided with a spur wheel 13 1 which engages with a similar wheel 135' on the travelling wheel axle 136 of the vehicle 1 carrying the machine. Preferably this wheel 135 is adapted to engage a rack 13S laid between the arallel rails 2. When it is desired to travel the vehicle 1 along the rails 2 without this intermittent motion but steadily the other travelling wheel axle 139 is rotated by means of bevel gearing. 14:0, chain and sprocket wheels 142,Figs. 15,16 and 17, actuated from the vertical telescopic shaft 85. A clutch 143 is arranged So that either the one travelling mechanism or the other is in gear. Preferably the pinion 135 on the vehicle axle 136 is comparatively long and slides on a helical key 14 1, Fig. 241, on the axle 136 so that the machine may be brought into pitch with the bricks on alternate layers or courses and may be adjusted slightly if desired as the laying proceeds. This may be accomplished by means of a lever 145 and clutch 1 16 provided on the pinion 135 which engages the rack 138 between the rails 2.

To ensure that the links of the conveyor chain 3O will be in proper position toreceive the bricks from the feeding mechanism the spindle 1 17, Fig. 17,- of the lower conveyor chain roller 29 is provided with a worm wheel 1418 which engages with a worm 1 19' mounted on the spindle 89 driven from the spindle 86 of the feed driving mechanism which spindle 86 is also provided with a coupling 150, Fig. 16, which consists of two discs connected together by a T headed. bolt passing through one disc and engaging V aslot formed in the other discQ Beside the motor 5 on the cantilever frame 32'" a mortar tank 73, Fig. 18, is arranged and on the downwardly hanging laying frame 44 a secondary tank 74: isarranged. The secondary tank 'i'l is supplied from the first tank by means of a pipe 151 and delivers the mortar on to the topof the bricksbein laid by means of an'other' pipe or pipes 152;

When one course of bricks has been laid the cantilever frame 32% is raised the necessa'ry distance (one brick and the mortar joint) by means of the rotation of the verti V cal. screwed Shafts 80;
